The classified intelligence President Donald Trump shared with Russian diplomats last week came from Israel, reports say.

The New York Times, citing a current and a former American official, reported the newest wrinkle in a story that has consumed the Trump administration since Monday night. NBC News and CNN also have sources saying Israel is the partner who supplied the intelligence that Trump shared with Russian Foreign Minister Sergei Lavrov and Ambassador to the U.S. Sergey Kislyak in a White House meeting last Wednesday.

According to The New York Times' anonymous sources, who were not authorized to discuss the matter, Trump shared intelligence about an Islamic State plot, with "at least some of the details" coming from Israel. They also said Israel asked the U.S. to be careful with the same intelligence.

Israeli officials would not confirm to The New York Times if they were the source of the information, but Israeli Ambassador to the U.S. Ron Dermer gave no indication the report would strain the relationship between the nations.

"Israel has full confidence in our intelligence-sharing relationship with the United States and looks forward to deepening that relationship in the years ahead under President Trump," Dermer said.

National Security Adviser H.R. McMaster on Tuesday afternoon defended Trump's comments during last week's meeting, which he described as "wholly appropriate." He also said "the president wasn't even aware of where this information came from. He wasn't briefed on the source."

In a pair of Tuesday morning tweets, Trump said "as President I wanted to share with Russia (at an openly scheduled W.H. meeting) which I have the absolute right to do, facts pertaining to terrorism and airline flight safety, Humanitarian reasons, plus I want Russia to greatly step up their fight against ISIS & terrorism."
